I've become very interested in the way that American Capitalism managed to make so much progress -- genuine, real progress -- in the 20th century and then stalled out so dramatically in the early 21st. This is a great video analyzing the rise of American power (which dovetails with American worker power in the early 20th century) and how the process of dismantling that worker power in favor of capitalist power has led to our current state of bloated neoliberalism.
